What is Mean Absolute Deviation (MAD)?

Back

Mean Absolute Deviation is a measure of the dispersion of a set of data points. It is calculated by taking the average of the absolute differences between each data point and the mean of the data set.

What is the difference between a preimage and an image in geometry?

Back

A preimage is the original figure before any transformation, while an image is the resulting figure after the transformation has been applied.

Front

What does the Pythagorean Theorem state?

Back

The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b). It is expressed as: a² + b² = c².

Front

How do you find the y-intercept of a linear function?

Back

The y-intercept of a linear function can be found by setting x = 0 in the equation of the function and solving for y.

Front

What is the Slope-Intercept Form of a linear equation?

Back

The Slope-Intercept Form of a linear equation is given by the formula y = mx + b, where m is the slope and b is the y-intercept.

Front

What does it mean for two functions to intersect?

Back

Two functions intersect at points where their outputs (y-values) are equal for the same input (x-value).

Front

How do you calculate the slope of a line?

Back

The slope of a line is calculated by taking the difference in y-values divided by the difference in x-values between two points on the line, expressed as (y2 - y1) / (x2 - x1).

Front

What is a linear function?

Back

A linear function is a function that graphs to a straight line and can be expressed in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the formula for calculating the area of a triangle?

Back

The area of a triangle can be calculated using the formula: Area = 1/2 * base * height.

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis), used to graph points, lines, and curves.
